A glass fiber grid reinforced layer is arranged on the cement concrete pavement, and then an asphalt concrete surface layer is laid thereon. The paved road has a significant effect on preventing reflection of cracks in the base layer, reducing rut on the road, and prolonging the life of the road. Glass fiber grid has the characteristics of high tensile strength, low elongation, no creep, good compatibility with asphalt mixtures, stable physical and chemical properties, high temperature resistance, strong interlocking and restrictive effects, etc., its main role is uniform Transmit the axial load and change the reflected crack stress from vertical to horizontal.
The use of glass fiber grids can enhance the overall tensile strength of the asphalt mixture, effectively improve the stress distribution of the pavement structure, and resist and delay the occurrence of reflective cracks in the asphalt concrete pavement caused by the cracks in the base layer of the pavement, thereby increasing the service life of the pavement.
